CAR-END DOOR.

andv that. is; readily and easily opened and.

closed. without. the use of guideways, lugs or other parts positioned remotely from the door: frame and projecting outwardly from the end. structure where they are liable to be; broken or bent out. of line, should the end: become. warped, or distorted by load.

thrusts, weaving of the car and other causes; the provision of a door construction having. locking mechanism therein adapted to automatically lock the door to the frame upon its being closed and which can beunlocked. only from the inside. of the car; and such other objects and advantages as. may, be. found: to obtain in the, structure. hereinafter set forth or claimed.

In the; accompanying drawings, forming a part ofthis specification, and. showing, for purposes of exemplification, a preferred form and. manner in which the, invention may be embodied and practiced, but with? out. limiting the claimed invention specific.-

ally to such illustrativeinstance or instances:

Figural isan end elevational view of a.

of the. arrows; and V Fig. 7 's. a horizontal sectiontaken on the line 'Z-7. of Fig. 5 looking in the direction Application filed June 22, 1923. SeriaLNo. 647,026.

Fig. 8 is an enlarged fragmentary view showing the arrangement of the locking mechanism.

The sheet metal. end 10 comprises a plu rality of sections 11 riveted together as shown at 12', each section being provided with horizontal corrugations 13 for the purpose of reinforcing, strengthening and rigidifying the end structure that is subjectedlto warping, weaving and load thrusts resulting from various causes among which is the movement of the contents. of the car when the car is stopped and started One of the sections 11. is provided with an opening 14:. into which is positioned. a door-frame 15." The door frame 15 is provided with flat side walls 16 andtop and bottom walls 171 These walls l6and 17 are bent at one end to provide. flanges 18 which are olfset as shown at 19 to provide. another flange 21 that fits within the opening so that the flange portions; 18" are. flush with the edges 22 of the end sheet 11 to provide a watertight joint. The horizontal corrugations opposite the door frame terminate a short distance there from to provide flat surfaces 28 to which the flanges 21 are secured on the inside of the car by rivets 24.

(last integral with the walls 16 and 17, a short distance from their outer edges 25,is a flange 26 which is also flanged transversely to provide a wall 27. The flange 26and the wallQTextend continnously around the outer edges 25 of the walls 16 and IL? and form a continuous groove or channel 28. Two brackets 31 are secured by rivets 29 to the underside ofthe bottom wall 17; said braolr ets having.downwardly and outwardly extending portions 352 and horizontal bearing members 33 that are provided with slots or openings 34 into which a pin 35 may bear.

A: door 36 has secured to it at its lower end,

. by rivets 37, a hinge member or leaf 38 that is curled, as shown at 39 to receive the pin 35' and said door has formed. thereona continuous marginal flange 4;l that enters into the channel 28 and engages tightlytherein 45 having a vertical flange 46 extending transversely to the flange 45 and there is also provided a vertical web 47 that strengthens the portion 44 and flanges 45 and 46. The web 47 and the flanges 45 and 46 form a pocket 48 into which-the he'adof a gravity latch automatically engages when the door is closed. Two gravity latches 51, onefor each side wall 16, are pivoted on rivets 49, on the inside of the frame, close to the upper ends of the Walls 16, each latch having a portion 52 extending outwardly in the direction-of the door. The portion 52 is bent at 5 3 to provide anoutwardly extending oflset portion 54 having a head 55 curved at 56 so that when the door is closed the flange 46 will push the latch upwardly so that the flange 46 may pass thereunder and the head55 may drop by gravity into the pocket 48. This head 55 also has a straight edge 57 that makes contact with'the flange 46 when the head 55 is in the pocket 48. y I

To limit the downward movement of the latches, a lug or projection 58 is provided on each of the walls 16 beneath the portions 52 of the latch. Thislug is so positioned that it is sufiiciently high to hold the latch in position to be raised by the flange 46 when the door is being closed.

The upward movement of thelatch is lim ited the top wall 17 oftheframe.

If desired, a handle 59 may be'fastened on the outside of the door to facilitate its opening and closing.

It will be manifest from the foregoing that the corrugations of the sheetmetal end may extend in directions other than the di rection herein shown and also the shape of the doorstructure may be other than that illustrated herein.

The invention as hereinabove set forth is embodied in a particular form of construca tion but may be variously embodied within the scope of the claims hereinafter made.

I claim: a 1. An end structure for railway freight cars having an opening therein, a metal frame positioned within said opening, said frame having flanges secured to theinner face of said end structure, said frame having a member integral therewith andextending. from the outer surface of said frame, said.

member together with said frame forming -tion for engagement with the member proposition."

a continuous channel, a metallic door hinged to the bottom of said frame, said door having a continuous marginal edge engaging within said channel when said door is in closed position, a member secured to the inner face of said door near the upper end thereof, said member providing a pocket, a latch pivotally mounted on the inner face and near the upper portion of the side of the frame, said latch having a projecting portion fitting in the pocket of the member on the door, and a lug on theside ofthe frame for supporting the latch in position for engagement with the member providing the pocket.

:2. An end structure for railway freight cars having an opening therein, said end structure having reinforcing corrugations formed therein, certain of thecorrugations stopping short of the opening, a rectangular metallic frame positioned within the openmg, sald frame having flanges secured to i the inner face of said end structureysaid frame having a member integral therewith;

. and extending from the outer surface of said frame, said member together with said frame forming a continuous channel, a metallic' door hinged. to the bottom of said frame,

engaging within said channel when said.

said door having a continuous marginal edge door is in closed position, a member secured tothe inner face of said door near theupper end thereof,said member providinga pocket, a latch pivotally mounted on the inner face and near the upper portion ofthe side of the frame,-said latch having a projecting portion fittingin the pocket of the member on the door, and a lug on the side of the frame for supporting thelatch inposiing therewith a channel, a door hinged to the V frame, said door having a flangeadjacent the margin thereof and adapted to enter the said channel when the; door is in closed 4.
